    • 16cd demonstrated that o-(dimethylaminomethyl) phenyllithium, which is structurally analogous to 1, forms three isomeric chelated dimers in ethereal solvents: one with both nitrogens coordinated to one lithium of the dimer and two in which each lithium bears one chelating group. We performed preliminary calculations for the three corresponding plausible isomers and found that III is the most stable isomer among them: see Supporting Information.
